    Hello, I'm trying to find the equivalent resistance, but I'm having doubts with the short circuit, what influence does it do to the circuit?

    Normally a short circuit for example in parallel with a resistor would make that no current goes through that resistor, but in this case I'm not understanding it.
    thanks

    Try labelling each node and redraw the circuit with all the nodes represented as a single point on the diagram - the "short circuit" is really a node connection. In that case the 30Ω, the 12Ω, the 60Ω and the 10Ω all connect at that node.

    It may then become clearer as to the next step in reducing the circuit.

    xiiii you're right... the problem was i looked at the circuit and said immediately, it's a short circuit, and didn't even consider anything else.

    well, problem solved.
    thanks :)
